Fixed inductors have a wide variety of applications in electronics, owing to their ability to store energy due to their inductance. Among them, PM20-221K is a common type of fixed inductor which can be used in many power supplies. In this article, we discuss the application field and working principle of PM20-221K.

Application Field

PM20-221K fixed inductors are primarily used in power supplies where higher-current applications require a greater level of efficiency and reliability. They are also suitable for various power converters, such as switching mode power supplies, SMPS, and other higher-current applications. The main advantage of PM20-221K is that it has a high voltage stability and the current diodes in the inductor protect against peak voltage. Also, the built-in feature of the inductor helps to reduce the size of the application. In addition, the inductor can be used to filter AC input voltage.

Working Principle

PM20-221K fixed inductors work based on the concept of electromagnetic induction. The current in the coil builds a magnetic field which induces a voltage across it. As a result, an opposing magnetic field is created, resulting in the restriction of current in the coil. The inductance of the coil affects how much current is restricted. The amount of inductance determines how much energy can be stored in the coil. The higher the inductance, the more energy can be stored in the coil.

PM20-221K has a unique design which helps to reduce power loss and improve power efficiency. The inductor is designed with permanent magnets, so it can store more energy. Also, the inductor contains high-quality ferrite core which adds to the efficiency of the inductor. Furthermore, the inductor has a low DC resistance which ensures that the current flow is low and efficient.

In addition, the inductor has a wide temperature range which ensures that it will not be destroyed by extreme changes in temperature. The PM20-221K fixed inductor also has a high surge current capability, allowing it to handle high-load conditions with ease. Additionally, the inductor is designed with heavy-duty construction which increases its durability.

Conclusion

PM20-221K fixed inductors are a great choice for many of the higher-current applications. With their high level of efficiency, wide temperature range, and heavy-duty construction, they are capable of handling a variety of applications. The working principle of the inductor relies on electromagnetic induction which allows it to store energy due to its inductance. In short, PM20-221K fixed inductors are a great choice for power supplies, power converters, and other applications requiring high-current.
